石英Cron触发器处理夏时制的方法 [英] Ways to deal with Daylight Savings time with Quartz Cron Trigger

问题描述

我有一个石英cron触发器，看起来像这样：

I have a quartz cron trigger that looks like so:

<bean id="batchProcessCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="batchProcessJobDetail" />
    <property name="cronExpression" value="0 30 2 * * ?" />
</bean>

如果我在2-3am期间发生了几种配置，该如何解决？有公认的最佳实践吗？

How should I solve this, if I have several configurations that happen within the 2-3am period? Is there an accepted best practice?

基本上说处理。但是我的问题是如何！

Basically it says "Deal with it." But my question is how!

推荐答案

我使用一个单独的触发器解决了这个问题，该触发器仅在开始日期（一小时前）触发东部夏令时凌晨2点至凌晨3点之间发生的配置的DST。

I solved it using a separate trigger that only fires (an hour early) on the beginning date of DST for the configurations that happen between 2am and 3am Eastern.

似乎很笨拙，但可以正常工作...

Seems kludgey, but it works...
